According to documents filed in district court, A&W claims the Zubia family, which owns and operates Papa Burgers locations in El Paso and Albuquerque, "knowingly and willfully directed, oversaw and actively engaged" in trademark infringement.

Allowing Papa Burgers to continue using the name would cause A&W "immediate and irreparable harm" as the use of the name “is likely to confuse consumers and cause customers to believe” incorrectly that Papa Burgers and its products are affiliated with the A&W brand.

In a statement sent to the Times, A&W said it wants Papa Burgers to "discontinue its use of 'Papa Burgers' for its restaurant chain."

It's also seeking "compensatory damages," attorney's fees and other costs.
